Rijnzathe 30 3454 PV DE MEERN Executive summary Rapid application development platforms provide a graphical model driven approach with pre-built application components which allow users to visually construct complex processes and applications without coding. This enables both technical and business individuals to orchestrate and deploy business applications with ease and speed. The right model driven development platform provides significant productivity advantages over traditional development methods and enables project delivery by smaller yet faster teams. Whether your business processes are unique, you need to distinguish yourself from the competition or you need the ability to adapt to fast changes in the market you operate in; rapid application development supports these needs. Key benefits: ✓ Cost effective and time saving ✓ Accelerate innovation by 9-12 months ✓ Easy to make adjustments ✓ Tailor made; use what you need ✓ Easy to integrate with current IT systems ✓ Simplified lifecycle management ✓ No coding ✓ Fast delivery ✓ Responsive applications for every platform Rapid Application Development Intro In today's world, markets change fast and companies need to be flexible to adapt to these changes. Also most companies find themselves in challenging environments due to fierce existing competitors and disrupting new start-ups. This requires an IT landscape that is able to quickly adapt, to support the organisation’s business, rather than the other way around, where the business needs to adapt to cope with the existing IT landscape. Developing transformative or disruptive applications at high speed to keep up with the changing markets, requires rapid experimentation, frequent iteration, and close collaboration between business and IT. There are online platforms that make it easier than ever to create new applications and enable you to adapt to the ever faster changing market demands. They can be used for quickly building a prototype, integration with core systems and, services or to deliver a complete multi-channel experience on top of your existing IT systems. These platforms are called “Application Platforms as a Service” (aPaas) and in combination with Rapid Application Development it can enhance every unique business processes very fast. So what is Rapid Application Development exactly? And what is this so called Application Platform as a Service? Maybe even more important: How can it help your organisation? In this article we answer these questions in a practical way. After reading it you will understand the basics of this powerful software development & project management approach. Rapid Application Development What is Rapid Application Development? “​A form of application development in which the time required for development is reduced, so that changing requirements during the course of development do not invalidate the end product; abbreviated RAD​” - Oxford Dictionaries RAD is a software development approach that uses minimal planning and enables organizations to develop software faster. Especially in combination with aPaaS RAD is significantly faster than traditional development. RAD focuses on the gathering of customer wishes and requirements and prototypes that the customer will test during the development process. This model divides the analysis, design, construction and the testing phases of the software development process into short cycles, called sprints. Each sprint takes one or two weeks and results in a working prototype that serves as a working model that forms an immediate part of the final product. Therefore, there is little waste of time and effort, and the customer can see and test the results. Model Driven Development As mentioned before, RAD is a software development approach. Model driven development (MDD) is a software development methodology that focuses on leveraging a data model, which is a conceptual model of all topics related to a specific process. The MDD methodology is meant to increase productivity by simplifying the architecture design, simplifying application development and optimising system compatibility. Model Driven Development is most effective if its models are created from the users point of view. These models must make sense from the point of view of a user that is familiar with the domain and they form the basis for implementing applications. The models are developed through extensive communication among product managers, designers, developers and users of the application domain. As the models approach completion, they enable the development of software and systems. So how can you combine RAD and MDD? This is where aPaas comes into play. Rapid Application Development How does aPaaS fit in this picture? Application platform as a service (aPaaS) is defined as application infrastructure functionality, enriched with cloud characteristics and offered as a service. aPaaS is a genre of cloud hosting platform developed for designing, creating, installing and managing tailor-made business applications. It also includes resources such as infrastructure, data security, data management and user interfaces. In simple words, it is a sole environment that allows speed and agility across the whole application process. When developing or modifying applications on an application platform based on MDD, developers no longer have to concern themselves with low-level functions. Instead, they can focus on interfacing directly with their platform, rather than having to drill down to the system functions of the machine. They don’t even have to write a single line of code. The platform makes it easier to track and log changes throughout a system and it is also able to operate as an interface between applications and infrastructure, thereby creating a more fluid, better secured, and simplified computing model. For example, a company should starts by defining the models on the platform. These models are immediately available so they can use them in the processes that the company wants to build. With a simple drag and drop interface they can then create those business processes that make the company unique. They can even design the user interface and still haven’t written any code. The system itself will be only as productive and secure as the software and hardware involved. That is why aPaaS solutions are hosted in secure data centers and comply with the highest possible security, data integrity certifications and, laws. Rapid Application Development So how can RAD help your organisation? Companies have to deal with dynamic market needs, increasing customer expectations and higher service levels. By combining RAD and aPaas we enable your company to fulfill these needs with fast and flexible IT solutions at a fraction of the costs and delivery time, compared to classic development projects. Our approach Based on our experiences we have learned that the best way to start with RAD is based on these three principles: 1. Start small​. Start your RAD journey with one simple process. This way you will build up experience, align risk management and meet with governance. 2. Learn​. Learn from the previous experiences and use these ‘lessons learned’ and “best practices” to enter the next phase. 3. Scale up​. Now everything is in place to scale up. Any organization can now move forward and start integrating other systems, enhance or fully automate current business processes and add new features. The combination of RAD and aPaaS can help your organisation in unlimited ways. You can create anything from CRM systems to client portals and from order management systems to the automation of business processes. What will be your first project? Rapid Application Development Who are we? EsperantoXL ignites the creativity required to develop innovative new applications and processes by combining visual data modeling, synergetic development and agile project management. We will make your organisation scalable and flexible based on your own IT infrastructure, using RAD and aPaaS. By building on top of your existing systems, we’ll make sure you get the most out of the latest technologies. We’ve been doing this with great results for the past 15 years by automating business processes and quickly developing and managing new applications. What’s our secret?

  • Conceptual Modelling and Humanities
    Joint Proceedings of Modellierung 2020 Short, Workshop and Tools & Demo Papers Modellierung 2020: Short Papers 13 Conceptual Modelling and Humanities Yannic Ole Kropp,1 Bernhard Thalheim2 Abstract: Humanities are becoming a hyping field of intensive research for computer researchers. It seems that conceptual models may be the basis for development of appropriate solutions of digitalisation problems in social sciences. At the same time, humanities and social sciences can fertilise conceptual modelling. The notion of conceptual models becomes enriched. The approaches to modelling in social sciences thus result in a deeper understanding of modelling. The main aim of this paper is to learn from social sciences for conceptual modelling and to fertilise the field of conceptual modelling. 1 The Value of Conceptual Modelling 1.1 Computer science is IT system-oriented Computer system development is a complex process and needs abstraction, separation of concerns, approaches for handling complexity and mature support for communication within development teams. Models are one of the main artefacts for abstraction and complexity reduction. Computer science uses more than 50 different kinds of modelling languages and modelling approaches. Models have thus been a means for system construction for a long time. Models are widely used as an universal instrument whenever humans are involved and an understanding of computer properties is essential. They are enhanced by commonly accepted concepts and thus become conceptual models. The main deployment scenario for models and conceptual models is still system construction (with description, prescription, and coding sub-scenarios) although other scenarios became popular, e.g. documentation, communication, negotiation, conceptualisation, and learning. 1.2 Learning from Digital Hunanities Digital humanities is becoming a hyping buzzword nowadays due to digitalisation and due to over-applying computer technology.

  • Conceptual Model Evaluation. Towards More Paradigmatic Rigor Jan Recker1
    Conceptual Model Evaluation. Towards more Paradigmatic Rigor Jan Recker1 1 Centre for Information Technology Innovation Queensland University of Technology 126 Margaret Street, Brisbane QLD 4000, Australia [email protected] Abstract. Information Systems (IS) research has so far been primarily con- cerned with the development of new modeling languages, techniques, and methods. Also, evaluation approaches have been developed in order to assess the appropriateness of a modeling approach in a given context. Both modeling and evaluation approaches, however, lack epistemological rigor, leading to problems regarding the applicability of a certain modeling language in a given context on the one hand, and regarding the feasibility of certain evaluation ap- proaches towards certain modeling questions on the other hand. We therefore argue for a philosophical-paradigmatic discussion of evaluation methods for conceptual modeling languages in order to assess their applicability in given modeling contexts and present our research in progress towards a framework for paradigmatic discussion on model evaluation. Keywords. Philosophy, modeling methods, information modeling, research evaluation 1 Introduction The importance of information systems (IS) for successful businesses is widely rec- ognized [1]. Their implementation is preceded by their development through design methodologies which utilize information models to specify IS on a conceptual level. Such conceptual models have been successfully employed throughout IS theory and practice. This has led, however, to the proliferation of an enormous amount of avail- able modeling approaches. The “flooding” of the IS discipline with a multiplicity of conceptual modeling approaches consequently leads to an immanent need for com- paring and evaluating existing modeling methods in order to determine which ap- proach is most appropriate for a given modeling task.

  • On Using Conceptual Modeling for Ontologies
    On Using Conceptual Modeling for Ontologies S. Spaccapietra1, C. Parent2, C.Vangenot1 and N. Cullot3 1 Database Laboratory, EPFL, 1015 Lausanne, Switzerland [email protected], [email protected] 2 HEC-INFORGE, University of Lausanne, 1015 Lausanne, Switzerland [email protected] 3LE2I Laboratory of Business, University of Burgundy, 21000 Dijon, France [email protected] Abstract. Are database concepts and techniques suitable for ontology design and management? The question has been on the floor for some time already. It gets a new emphasis today, thanks to the focus on ontologies and ontology services due to the spread of web services as a new paradigm for information management. This paper analyzes some of the arguments that are relevant to the debate, in particular the question whether conceptual data models would adequately support the design and use of ontologies. It concludes suggesting a hybrid approach, combining databases and logic-based services.1 1. Introduction Nowadays, all major economic players have decentralized organizational structures, with multiple autonomous units acting in parallel. New information systems have to handle a variety of information sources, from proprietary ones to those available in web services worldwide. Their complexity is best controlled using a network of coordinated web services capable of grasping relevant information wherever it may be and exchanging information with all potential partners. Data semantics is at the heart of such multi-agent systems. Interacting agents in an open environment do not necessarily share a common understanding of the world at hand, as used to be the case in traditional enterprise information systems.

  • A Multi-Paradigm Modeling Framework for Modeling and Simulating Problem Situations
    Proceedings of the 2014 Winter Simulation Conference A. Tolk, S. Y. Diallo, I. O. Ryzhov, L. Yilmaz, S. Buckley, and J. A. Miller, eds. A MULTI-PARADIGM MODELING FRAMEWORK FOR MODELING AND SIMULATING PROBLEM SITUATIONS Christopher Lynch Jose Padilla Saikou Diallo John Sokolowski Catherine Banks Virginia Modeling, Analysis and Simulation Center Old Dominion University 1030 University Boulevard Suffolk, VA 23435, USA ABSTRACT This paper proposes a multi-paradigm modeling framework (MPMF) for modeling and simulating problem situations (problems whose specification is not agreed upon). The MPMF allows for a different set of questions to be addressed from a problem situation than is possible through the use of a single modeling paradigm. The framework identifies different levels of granularity (macro, meso, and micro) from what is known and assumed about the problem situation. These levels of granularity are independently mapped to different modeling paradigms. These modeling paradigms are then combined to provide a comprehensive model and corresponding simulation of the problem situation. Finally, the MPMF is implemented to model and simulate the problem situation of representing the spread of obesity. 1 INTRODUCTION When building models and simulations, it is desirable to have a well-defined problem and an agreed upon solution for representing that problem, yet most models depart from this premise. This is difficult to achieve when representing problem situations where there is no agreed upon specification due to differences in opinions of the team (Vennix, 1999). Modeling this type of problem has been addressed by reaching a consensus on what the problem is as proposed in soft-systems methodology (Checkland, 2000).

  • A Conceptual Model of Software Development
    Extracted form Ph. Kruchten: Software project management with OpenUP Draft April 2007 A Conceptual Model of Software Development A software project is temporary endeavour intended to create a new software product or service, or the software part of a software-intensive system. It is temporary in the sense that it has a definite beginning and a definite end, in contrast with a continuous endeavour, such as running the IT operations of an organization. A software project has specific and sometimes conflicting objectives and many constraints of diverse nature, mainly technical, temporal and financial. Software project management is therefore the art of balancing competing objectives, managing risks, and overcoming constraints to successfully deliver a product which meets the needs of both customers and users (the customer paying the bill not always being the end-user). A conceptual model of software development To explore the many facets of software project management, we will first introduce a conceptual model of software development. This model (or ontology) of software projects is organized around eight key concepts and their relationships: 1. Intent 2. Product 3. Work 4. People 5. Time 6. Quality 7. Risk 8. Project Intent The concept of Intent denotes what the project is trying to achieve. The Intent defines the scope of the project, the intentions and hopes of the key stakeholders, the objectives. While we think of the intent as “the requirements” or “the specification”, in practice Intent may take many diverse forms: a set of tests that the product must pass contributes to define Intent. A set of software problem reports that must be dealt with also indirectly defines Intent.

  • Ontology and Information Systems
    Ontology and Information Systems 1 Barry Smith Philosophical Ontology Ontology as a branch of philosophy is the science of what is, of the kinds and structures of objects, properties, events, processes and relations in every area of reality. ‘Ontology’ is often used by philosophers as a synonym for ‘metaphysics’ (literally: ‘what comes after the Physics’), a term which was used by early students of Aristotle to refer to what Aristotle himself called ‘first philosophy’.2 The term ‘ontology’ (or ontologia) was itself coined in 1613, independently, by two philosophers, Rudolf Göckel (Goclenius), in his Lexicon philosophicum and Jacob Lorhard (Lorhardus), in his Theatrum philosophicum. The first occurrence in English recorded by the OED appears in Bailey’s dictionary of 1721, which defines ontology as ‘an Account of being in the Abstract’. Methods and Goals of Philosophical Ontology The methods of philosophical ontology are the methods of philosophy in general. They include the development of theories of wider or narrower scope and the testing and refinement of such theories by measuring them up, either against difficult 1 This paper is based upon work supported by the National Science Foundation under Grant No. BCS-9975557 (“Ontology and Geographic Categories”) and by the Alexander von Humboldt Foundation under the auspices of its Wolfgang Paul Program.
